STARTING DEVICE FOR. FLYING-MACHINES.

Specification of Letters Patent.

Patented Apr. 23, 1912.

. To all whom it may concern:

Be it known that I, KARL VoLLER, a subject of the German Emperor, and resident of 12 Scharnhorststrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Starting Devices for Flying-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable-others skilled in the art to which it appertains to make and use the same.

The present invention relates to a starting device for flying machines consisting in an arrangement of devices on the machine by means of which at the moment of starting the latter is raised from the ground so that all friction due to contact with the ground is eliminated.

According to the invention the starting device acting on the flying machine is connected with a boat pivotally suspended from the flying machine, so that the rising by means of the starting device can be effected either on land or on water.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of a flying machine with the device in the position which it has before the rising action, Fig. 2 a like view with the device in the position which it has after the rising action, while Figs. 3, 4, 5 and 6 show details.

In the construction shown the starting device is such that the flying machine is launched by anexplosion of powder. For this purpose there is an explosion chamber a (Figs. 1, 2 and 4) in the head of which is a charge of powder I). This small chamber carrying the charge is closed by a screw 0, which-carries an igniting device d of any suitable construction. Two ipes 6 connect the explosion chamber a with clyinders respectively, which are pivoted to the flying machine one on each side thereof at g. In the drawing only one cylinder 1 is visible, since the second cylinder on the other side is behind the first and is hidden there. In each cylinder 1 there is a hollow piston rod h (Figs. 1, 2 and 3) having a piston z. The

outer end of the piston rod is pivoted at is.

to the boat Z which is suspended from the flying machine by parallel rods m In the position of rest the flylng apparatus has the position shown in Fig. 1 relative to the boat. The piston rods h are pressed into the cylinders f by springs n (Fig. 3). Moreover, bolts 0 are inserted in the deck of the boat, and are pressed downward by the weight of the flying machine against the action of springs 72. When the flying machine is to rise, the charge of powder is ignited by the firing device. The powder gases pass through the pipes e into the cylinders f and expand therein and also in the bore of the piston rod h. In this manner the piston rods h are pressed forcibly downward and the boat is pressed firmly against the ground or on to the surface of the water. The cylinders f areinclined at a certain angle to the horizontal. The force is therefore exerted in this direction and gives a vertical and a horizontal component. Since the ground or water ofl'ers resistance to the boat 1, which resistance against horizontal movement may be increased by spurs g normally folded against the under surface of the boat, the flying machine is raised into the osition shown in Fig. 2 by the. action of t e powder gases, and at the same time receives an impulse forward, -which added to the power of the motor gives the flying machinethe necessary speed for flying. The launching of the flying machine is also aided by thesprings p.

Having thus described my invention and the best means I know of carrying the same into practical efl'ect, I claim 1. In a flying machine, a starting device carried by the flying machine, a boat pivotally suspended from the flying machine and between which latter and the boat there is a relative movement in starting, and means forming a pivotal connection between the starting device and the boat.

2. In a flying machine, a starting device carried by the flying machine, a boat, links pivotally suspending the boat from the flying machine and between which latter and the boat there is a relative movement in starting, and means forming a pivotal connection between the starting device and the boat.

3. In a flying machine, a starting device carried by the flying machine, a boat pivotally suspended from the flying machine and between which latter and the boat there is a relative movement in starting, means forming a. pivotal connection between the starting device and the boat, and folding spurs on the under side ofthe boat.

4. In a flying machine, a starting device carried by the flying machine, a boat ivotally suspended from the flyin mac ine and between which latter and the oat there is a relative movement in starting, a ivotal connection between the starting devlce and the boat, and spring bolts on the boatadapted to be under compression when the flying machine is at rest and to assist the launch of the machine.

In testimony whereof, I have signed this 5 specification in the presence of two subscribing witnesses.
